Complications from femoral artery access in dogs during heart

Abstract

BACKGROUND: The primary objective of this study is to evaluate the peri-procedural major and minor complications associated with percutaneous femoral arterial access using modified Seldinger's technique in dogs that underwent cardiac catheterization. METHODS: Medical records of 62 client owned dogs that underwent percutaneous femoral arterial access for interventional cardiac procedures were retrospectively evaluated. Post-procedural manual compression was used for hemostasis. Peri-procedural vascular access complications (that occurred from procedure time to discharge) were evaluated. Vascular access complications were divided into two groups: minor complications that did not require specific therapy and major complications that did require an intervention to address the complication associated with vascular access. RESULTS: The minor complication rate was 30.6% (19/62) with most dogs experiencing minor bruising and small hematomas. The major complication rate was 3.2% (2/62). Both major complications were associated with bleeding with one dog requiring blood transfusion and the other dog requiring fluid therapy. No peri-procedural mortality associated with vascular access was noted. CONCLUSION: This retrospective study suggests that percutaneous femoral arterial access using the modified Seldinger's technique with post-procedural manual compression for hemostasis is viable option for vascular access during cardiac catheterization and associated with no peri-procedural mortality in dogs. The lower rate of complications noted in this study may be related to operator experiences and as such complication rate at a single center may not reflect the experience at other centers.
